It should look like this:
<img src=”http://glutenfreepostv2.com/wordpress/wp-content/uploads/2009/04/holiday_ad.jpg” alt=”holidaybakingcompany.com” width=”239″ height=”65″/>
where the first part is where you want it to link to, the second (img src) is where it is uploaded (its location on your server) and the last part being its specific name and exact size.
I just discovered that if I leave the width=”” and height=”” parameters blank the images do not show up in IE8.0. They do show up in Google Chrome with the parameters left blank. I tried inserting values within the parameters or just removing the parameters and they seem to show up correctly in IE.
